IM'PRovEMENT IN HosE-Noz'zLEs.

Specification forming part of Letters/Patent No. 150,646, dated May 5,1874; application filed March 9, 1874.

, l To all whom it may concern:

Be it known that I, GEORGEl WILSON, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Hose-Nozzles; and I do declare that the following is a true and accurate description thereof, referience being had to the accompanying drawings! and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l is a sectional perspective view of Figure 2 is a sectional plan of the spiral core around which the hose is coiled. y

Like letters refer to like parts in both iigures.

This invention has for its object to so construct a hose-nozzle for the use of firemen that it will throw a volume of water to a greater distance with the same pressure and keep it more solid than the ordinary conical hosepipes heretofore used 5 and to this end it consists in twistingthe end of the hose around a spiral core inclosed in a suitable metallic case and terminating in a reduced end; also, in connection. with thev said core, a compressingsleeve, threaded on its outer end for contracting the extremity of the flexible nozzle, as more fully hereinafter set forth.

In the drawing, A represents the end of a hose, preferably of india-rubber, contracted at the extremity a to form a nozzle, its other end being provided with a coupling, b, for couplingit to the leading hose. B is a core-tube,

provided with a spiral, B', for a portion of its l Vthe spirals, and the hose coiled about the tube.

By screwing the sleeve O farther onto the tube the extremity of the flexible nozzle may be compressed, so as to contract its bore to any desired extent.

As it is a well-known fact that a projectile
